Mars’ Crater Impact Rate Gets an Update with the Help of Seismic Data
InSight has advanced our understanding of the Martian interior by using seismic techniques typically applied on Earth. One instrument, the Seismic Experiment for Interior Structure (SEIS) returned data that shows marsquakes from recent impacts of space debris on the surface. Compared to the orbitally-imaged catalog of craters, the seismically-detected events don’t seem to entirely match.
If you feel it, chase it: using seismic signals to detect tornadoes
The threat of destruction and injury the tornado chasers show viewers in the 2024 movie “Twisters” is real, so what can be done currently to warn against tornadoes, and how do we detect and track them using geophysics?
How Listening to Rocks Unveiled the Structure of an Aquifer
When features below Earth’s surface aren’t easily visible, geophysicists turn to their multi-disciplinary toolbox for answers. In a new study, geophysicists took a listen to ambient noise with seismometers to map out the complex structure of a Florida aquifer.
What’s shaking at Yale? A Raspberry Shake has some answers
Yale scientists discuss how to incorporate a low-cost, education-ready seismic sensor with coursework and outreach.
Nuclear explosion monitoring gets a new dataset
In order to monitor compliance with the Nuclear-Test-Ban Treaty, the CTBTO is developing ways to verify nuclear explosions. A new benchmark dataset based on (non-nuclear) experiments is one example.
Former intern finds curious signal in geyser eruption data
Seismic monitoring of Yellowstone’s Steamboat Geyser showed that signals appeared weaker in winter—because of snow cover.
